CTS is an acronym for Copper Tube Size. Oatey supports are sized based on CTS. For example; ½? CTS piping used in plumbing applications actually has a 5/8? outside diameter (OD), but is referred to as ½? pipe. ¾? CTS piping used in same application has a 7/8? OD, but is referred to as ¾? pipe. Pipe classified as IPS or Iron Pipe Size will have larger ODs than CTS and HVAC pipe ODs are smaller than CTS.
